[OSM-dev] Slippy map way forward -- OpenLayers and/or Mapstraction?

[Anselm Hook]

Much as I am endeared to tile.js I'd personally just suggest making sure
the backend can act as a WMS.  This would open the door to a variety of
possibilities including OL.

OL avoids speaking as to how the back end is supposed to keep up with all
the queries but probably squid can address that?  I'm presuming OL does
deterministic and quantized tile queries so that the HTTP requests for the
same tile geography are identical between different clients.  That's
really all that squid needs and it then doesn't require customizing
mapserver.
